4KMEDC300BW1 Dryer - Instructions

once the back is off remove belt from tentioner and remove v clip. smooth shaft with wd-40 and scotch brite , then install new idler replace v clip
and your done !!!

I looked for squeaky dryer within parts select and went with the 80%. I received the Maintenance Kit, replaced two rollers and it works like new. Amazing since this is the first time I have ever opened a dryer. The instruction sheet and parts were all I needed.

Took the old filter out and inserted the new one- works great!!

Rather than remove the front panels, door, control panel and drum, I noticed 1/4" metal screws on the back panel. There were approximately 6 holding the back panel in place. I did have to remove the top panel as well before removing the back. Once removed I had complete access to the broken idler pulley assembly. I immediately saw the broken pulley. I installed the new one with very little effort. Reset the belt according to instructions from the video. Reassembled, plugged in, hit start and enjoyed the sweet sounds of success. All told it took me about 20 minutes from start to finish.

Pulled out the old and slid in the new filter

My dryer starter squeaking in December 09 and the repairman told me that it would cost between $200-$500. I did not let him fix it as this machine is only 3 years old. When the part finally broke in April 10, I was ready to junk this and just buy a used dryer. My husband went on line and quickly figured out the part he would need to do the repairs. It cost under $20.00. Now my dryer is fixed and running and there are no squeaks. Thank you

I just inserted the door catch, which by the way fit in perfectly. Thanks. Took 5 seconds to repair.

Used socket set to remove the two hex-head screws from the bottom flange of the toe panel. Manually pulled the panel out at the bottom, pulled down, and removed the panel. Looked to right and found heater shield. Removed heather shield using socket set. Removed the two wires from the terminal block (had to use a little WD40 to loosen connection and wiped up afterwards). Removed the holding screw holding the heating element using the socket set. Pulled HARD on old heating element using pliers and a rag (protection from accidental cut-sharp edges). Once out, the new element slid in relatively easy. Screwed the new element back into place and re-connected the element wires, then put the heater shield back into place. Put the toe panel back into place. Tested and worked great! The only thing that made this "easy" but not "really easy" is that I had to really pull HARD on the old element to get it out...with the sharp edges and tight fit in play, you'll need to pay attention to safety when removing the old element.

I replaced the thermistor earlier, but the code was still flashing. I noticed the heater terminals were charred and pretty well covered in carbon. So, I replaced the heater, the thermostat and thermal fuse and replaced the 3/8" spade terminals on the heater wires. (These are hard to find - most electrical spades terminals are .250. Also, I crimped and soldered these for a connection with the lowest resistance possible). After all that, the code still flashed! I let the explatives fly, calmed down, and ran the control board test. (This is done by pressing "more time" "less time" "more time" "less time" in succession.) The control board was passing all the tests, but the thermistor test, and the only thing is in this circuit is the thermistor, the wires, the connector to the control board, and some circuit on the control board that involves a few resistors and the "brain" chip. So, I checked the terminals at the thermistor, the wires up to the control board and the connector at the board. The control board connector was fairly dust encrusted, so I unplugged it, cleaned the control board terminals and sucked away all the lint and dust. Finally, I carefully removed earch crimp terminal from the Molex connector (the white female connector) and cleaned and bent them to yield a better connection to the terminals on the control board. I put it all back together, and thus far it is working fine.

Unplugged dryer. Removed dial. Removed old timer (3 screws) and left wires attached. Installed new timer. Disconnected wires from old timer to connect on new timer. Plugged in dryer......everything worked again.

Received in two days, open box, installed part. Pretty easy, fast service. I'm a repeat customer and will use these guys in the future.

Removed the two screws under the lint trap
Opened the top (had to use flathead screwdriver to release latches)
Disconnected door switch harness from front panel
Removed 2 screws holding front panel on dryer
Lifted out dryer drum (previous belt had broken)
Vacuumed inside of dryer (found $3 in quarters!)
Put new belt around drum
Put drum back in dryer, using empty laundry soap bottle to support its weight
Looped belt around pulley and motor; secured pulley to dryer bottom
Made sure rear gasket thingy was aligned properly and drum turned freely
Put front panel back on
Re-attached door switch
Closed top and put screws back in under lint trap
Fired it up - WOOHOO!

I raised the top of the dryer, removed the front, the belt and the drum. Slipped off old rollers, installed new ones and new tensioner. Reinstalled drum and belt, bolted front back on and closed the top.

Used my Whirlpool Dryer User Instructions Manual and followed instructions and used the Cabinet Parts page to see the diagrams.

I had already taken the coil out of the heating housing to check for a break in the heating element. I took this time to vacuum out all the lint inside the cabinet. I slid the new coil into the housing and reattached the wires. Plugged the dryer back in and turned it on to make sure the coil heated up. It worked so I put all the screws back in and fastend the front back on and were in bussiness!
